In the year 2003 at the Longview State Correctional Facility
(in Texas), convicted death-row inmate Marcus Wright (Sam Worthington)
was an hour away from a lethal injection. He was approached one last
time by terminally-ill researcher Dr. Serena Kogan (Helena Bonham Carter).

She was there to have him sign a consent form, to
donate his body for a "noble
cause." He
would receive a "second chance" at life - believing wrongly
that he would help save the "human race."

He actually 'sold' himself
to Cyberdyne Systems Genetics Division (in San Francisco) for a single
kiss. He mused after the kiss:

"So that's what death tastes
like."

He became an advanced T-RIP (Resistance Infiltration
Prototype) hybrid machine (but with a human heart and brain).

He was
summarily executed, without any final words - his last view was Dr.
Kogan standing over him.

The film was noted for its very lengthy
kiss between them, beginning at the front door. The camera circled
around them as they continued kissing into the living room, and then
onto the sofa, in the semi-indulgent passionate moment.

The kiss
involved lipsmacking, sucking, licking, and culminated with additional
body grinding as Peyton laid atop Elena on the couch.

The kiss was about three and a half minutes long, not
enough to beat the record established by Kids in America (2005) -
see above, although it was probably the longest 'lesbian' kiss ever
recorded.

Director Vincenzo Natali's sci-fi horror film told about
a young
and rebellious, romantically-linked scientist couple:

Clive Nicoli
(Adrien Brody)

Elsa Kast (Sarah Polley)

The two conducted a secret, sophisticated
genetic cloning 'experiment' in which they spliced together human and
animal DNA, creating a hybrid creature.

They named the creature DREN after it rapidly evolved
into a bald, partly-human mutant adult female (Delphine Chaneac) -
a fantastical creature with striking slanted eyes, pointed tongue,
a toxic tail-stinger, and bird-like, multi-hinged legs.

Over time,
DREN became more troublesome and unstable, but also became infatuated
with Clive.

In the film's most remarkable scene of alien-human sex
(with hints of bestiality and incest), Clive had unconventional intercourse
with the creature when she wrapped her winged-arms around him, naked.
She voraciously kissed him, and persistently and eagerly sought sex
with him by getting on top and orgasmically expanding her retractable
wings - and he possibly impregnated her.

During the sex act in which
she moaned and cooed, she regenerated her phallic-like stinger - just
as Elsa arrived and caught them in the act.

The Adjustment Bureau (2011)

Fate-Altering,
Life-Changing Kisses

There were two life-changing kisses in this highly-speculative
sci-fi romantic thriller from director/writer George Nolfi, adapted from
a Philip K. Dick story, "Adjustment Team." It speculated
about fate, destiny and free-will orchestrated within an alternate
reality.

Gifted, young and charismatic NY
politician/congressman David Norris (Matt Damon) had just failed in
his first bid for the office of NY Senator. He had a chance meeting
in the Waldorf Astoria Hotel's men's rest-room with free-spirited,
off-kilter ballerina Elise Sellas (Emily Blunt) who was hiding in a
toilet stall (to evade security guards, actually Adjustment Bureau
agents, from a wedding she had crashed), and overheard him practicing
a concession speech. She made a deep impression upon him (and they
shared their first unexpected kiss). His subsequent off-the-cuff speech
was influenced by her - it was heartfelt, "authentic,"
and devoid of the usual political rhetoric, and would be a positive factor
in his second successful run for election four years later.

Although David was never supposed to see Elise again,
he unexpectedly met her about a month later during a city bus ride, but
the
Fates - represented by suited, hat-wearing operatives in the bureau
led by Richardson (John Slattery), objected to their second encounter.
The puppet-mastering job of the Adjustment Bureau agents was to make
minor adjustments, keep things on track, prevent ripple effects caused
by behavioral deviations, and if necessary, lobotomize brains (a "square-one
reset" or
recalibration) to have things go according to plan (according to a
grand scheme of things overseen by an unseen Chairman - God?). The
Bureau's efforts kept getting foiled by David's wild determination
to keep in touch with Elise, and they reestablished their relationship
and made love to each other.

Harsh warnings from Thompson
(Terence Stamp) cautioned that romance with Elise brought out David's
reckless and impulsive side and would distract his attention from his
need for accolades, crowds, and applause - and most importantly, it
would jeopardize his promising and predestined political career that
could lead to the Presidency. The Bureau caused Elise to fall during
a dance performance and sprain her ankle, and David thought that staying
with her would cause pain. After visiting her at the hospital, he
abandoned her and intended never to see her again.

However, in the climactic finale, David changed his
mind when he learned Elise was planning to marry her ex-fiancee. He
raced to Elise and in the courtroom's restroom, he begged for her
not to marry. He told her that the plan in a book was to keep them
apart: "This
says that you love me and that I love you, and that we're not supposed
to be together...But I know that I'm supposed to be with you because
of the way I feel. I love you and I don't care what happens. I want
to spend the rest of my life with you even if it's only a little while." Although
at first reluctant, she decided, "I'm coming with you." They entered
a trans-dimensional door into the NY Public Library - the office-hub of
all the operatives, and ascended the building to get to the Chairman's
office, to try to change their fate, plead their case, and rewrite their
destiny.

When surrounded on the roof with no way out, they professed
their love and passionately kissed - and the agents suddenly disappeared.
They learned from one of the AB agents that they had been tested, and
that their "inspiring"
love for each other had affected the Chairman. Although their romance
was considered "a serious deviation from the plan," their life's
path was rewritten so that they could be together.

The Twilight Saga: Breaking Dawn, Part 2 (2012)

Forever
Kisses

The fifth and final installment of the romantic vampire
Twilight saga found the two main teenaged protagonists at
peace and in love - "forever" - as a vampire couple:

Isabella ("Bella") Swan (Kristen Stewart)

Edward Cullen (Robert Pattinson)

They were seated together in a meadow of colorful
wildflowers. Bella removed her shield and gave Edward access to her
loving thoughts for the first time. A montage of the development
of their relationship was presented. In the background for the five
minute sequence, the soundtrack played "A
Thousand Years (Part 2)" by Christina Perri featuring Steve
Kazee:

("The day we met, Frozen I held my breath, Right
from the start, I knew that I'd found a home for My heart beats
fast, Colors and promises, How to be brave, How can I love when I'm
afraid to fall, Watching me stand alone, All of my doubt, suddenly
goes away somehow, One step closer. I have died everyday waiting
for you, Darlin' don't be afraid, I have loved you for a thousand
years, I love you for a Thousand more. Time stands still, Beauty
in all she is, I will be brave, I will not let anything take away,
Standing in front of me, Every breath, Every hour has come to this..."):

Bella: "I wanna show you something."
Edward: "What? (She closed her eyes and shared her memories) How did
you do that?"
Bella: "Been practicing. Now you know. Nobody's ever loved anybody
as much as I love you."
Edward: "There's one exception. (They kissed) Will you show me again?"
Bella: (She laughed and shook her head) "We've got a lotta of time."
Edward: "Forever."
Bella: "Forever." (They kissed again)

The film shifted from the meadow to the last page of
the Stephenie Meyer's book upon which the film was adapted, with
the following similar black text on white paper:

"We have plenty of time to work on it," I reminded him.
"Forever and forever and forever," he murmured.
"That sounds exactly right to me."
And then we continued blissfully into this small but perfect piece
of our forever.

Then after a wipe left, the text was shown as white on a black background,
with the last word "forever" in bold - the only word on the page.

In the final few minutes of the film as a tribute,
every actor with a speaking role in the entire film series
was credited and identified with a picture,
including these three major characters.
